2 Connecting to a DSM Data Collector

This section discusses using the configured Python environment to interact with the DSM Data Collector.

Python is a natively object-oriented language; methods such as opening a connection to the DSM Data

Collector involve using and interacting with the connection object previously created.

All subsequent REST API calls are defined between the open and close connection code segments shown in

the following subsections.

2.1 Open a connection

This code defines the REST API request and opens a connection to the DSM Data Collector by using the

HTTP POST call.

# login to DSM instance

# declare and define the payload variable

payload = {}

# define the REST API call

REST = '/ApiConnection/Login'

# build the complete REST API URL

completeURL = '%s%s' % (baseURL, REST if REST[0] != '/' else REST[1:])

# execute REST API call via the HTTP POST method

print connection.post(completeURL

,data=json.dumps(payload

,ensure_ascii=False).encode('utf-8')

,headers=header

,verify=verify_cert)

STDOUT

2.2 Close a connection

In a similar fashion, it is a good practice to close any open object connections prior to exiting a script as

shown in the following.

# logout from DSM instance

# declare and define the payload variable

payload = {}
